Yes, you are correct. One election cycle could have changed all of that, if the Democrats actually wanted to fix it. They had 4 years, and a majority. But instead of fixing all of that, they quietly increase funding to things like ICE, torture prisons, and genocide.
I love it when "stop bombing kids", or "stop sending people to torture prisons", or "stop bypassing Congress to spend money on Trumps projects" by the supposed opposition party is considered "idealism".
